Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8500 GT		45 Watts
GeForce GTX Titan		250 Watts
	Difference: 205 Watts (456%)

Memory Bandwidth

In theory, the GeForce GTX Titan will be 2153% faster than the GeForce 8500 GT overall, due to its greater data rate. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 275584 (2153%)

Texel Rate

The GeForce GTX Titan is quite a bit (more or less 5108%) better at texture filtering than the GeForce 8500 GT. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 183888 (5108%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan is superior to the GeForce 8500 GT, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 38376 (2132%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
